Biography

Greg Ganger is Professor in the Electrical and Computer Engineering & School of Computer Science. He has broad research interests in computer systems, including Operating systems, storage/file systems, security, networking, distributed systems. He is particularly interested in developing new ways of structuring computer systems to address technology changes and enable new applications. Most of his current research explores these topics in the broad context of storage systems and large-scale infrastructures within CMU's Parallel Data Lab (PDL), for which he serves as Director. See the PDL pages for more current information. Together with industry collaborators and other members of CMU's Parallel Data Lab (PDL).

His group has many ongoing projects in such areas as self-* (managing, tuning, ...) systems, device-embedded functionality, and computer infrastructure security. In addition to research and teaching, Professor Ganger enjoys spending time with his wife, Jenny, playing various sports (basketball, in particular), and occasionally sleeping. Of course, with the arrivals of Tim and Will, all of that became irrelevant

Education

B.S., 1991, M.S., 1993, 
Ph.D., 1995 from the University of Michigan.

Professional Background

Ganger spent 8/95 thru 11/97 as a postdoc in Frans Kaashoek's research group (PDOS) at the MIT Lab for Computer Science. During that time, he participated in the design and development of the exokernel operating system.
